    AutoCAD Import Issues - Detail Families

    Often times, I will receive a CAD detail drawing from a manufacturer that I need to import into Revit as a detail family.

    When importing from CAD, there always seems to be a myriad of issues. As a first step, I will open up the CAD drawing to clean it up in preparation for importing it into Revit. While in CAD, I will consolidate all the layers and purge unused items. Are there other things i can in order to have a smooth transition between CAD and Revit?

    Despite consolidating and purging unused layers, I will import it into Revit, and the view box is extensive, implying that there are hidden layers which expand the view box.

    Best to recreate them in Revit and not try to use the CAD detail... If you really have to use the CAD file, insert it into a generic annotation family. Helps with the formatting some.

      Also turn on all layers and make sure there are no elements in the distance. I'll usually start with a WBLOCK and select just what is visible in the detail drawing. That gives me file that is stripped of other elements usually. Purge All too. Remove any Named UCS.

      When you link/import adjust the Import Lineweights Settings so that the colors used get assign pens that better match the dwg's intended appearance. Also use Colors: Black and White so the layer colors aren't carried over.

        create a project that you use just for importing and creating details.
        This way you will create a "library" of these details for later use.

        Import them ONLY into this project file, and redraw them with revit linetypes that you have personalised in that linked project and that line up with your office template line types (thickness, colors, line styles, etc)

        Then when you need it in your actual project go and fish it from the "Details" project file using the "insert 2D view from file" option.

        This avoids importing cad layers into your actual projects which will really quickly fill your actual project up with useless and unpurgeable information.

          Really good idea. But I have a question, do you guys do this process customized for every project out there that you have? All these steps take a long time, and so far, by the short experience that I have, we never had enough time to do all these steps, rather barely to import the cad in detail families, then insert them into projects.

            Eventually you get to the point that you don't even import it into Revit and just create a quick drafting view based on the CAD file. I prefer getting a PDF detail over CAD.

              Linking, instead of importing, helps minimize the amount of issues.
